[2] => America
答案 0 :(得分:217)
array_values()
函数 [docs] 执行此操作:
$a = array(
3 => "Hello",
7 => "Moo",
45 => "America"
);
$b = array_values($a);
print_r($b);
Array
(
[0] => Hello
[1] => Moo
[2] => America
)
答案 1 :(得分:0)
使用array_keys()函数获取数组的键,并使用array_values()函数获取数组的值。
您要获取数组的值:
$array = array( 3 => "Hello", 7 => "Moo", 45 => "America" );
$arrayValues = array_values($array);// returns all values with indexes
echo '<pre>';
print_r($arrayValues);
echo '</pre>';
输出:
Array
(
[0] => Hello
[1] => Moo
[2] => America
)
您要获取数组的键:
$arrayKeys = array_keys($array);// returns all keys with indexes
echo '<pre>';
print_r($arrayKeys);
echo '</pre>';
输出:
Array
(
[0] => 3
[1] => 7
[2] => 45
)
答案 2 :(得分:0)
如果出于某种原因要重置数组的键计数,则
$array1 = [
[3] => 'Hello',
[7] => 'Moo',
[45] => 'America'
];
$array1 = array_merge($array1);
print_r($array1);
输出:
Array(
[0] => 'Hello',
[1] => 'Moo',
[2] => 'America'
)
